Abstract: A method and apparatus that controls a peak-current condition in a multi-die memory, such as a solid-state drive, by determining by at least one die of the multi-die memory whether a subsequent memory operation is a high-current memory operation, such as an operation to enable a charge pump of the die, an operation to charge a bit line of the die, or a program/erase loop operation, or a combination thereof. The die enters a suspended-operation mode if the subsequent memory operation is determined to be a high current memory operation. Operation is resumed by the die in response to a resume operation event, such as, but not limited to, a command specifically address to the die, an indication from another die that a high-current memory operation is complete. Once operation is resumed, the die performs the high-current memory operation.

Abstract: Described embodiments include logical units within a memory device with control circuitry configured to assign a logical unit address to the logical unit. Apparatus including a plurality of the logical units arranged in a daisy chain configuration and methods of assigning logical unit addresses to the logical units are also disclosed.

Abstract: Memory devices and methods facilitate handling of data received by a memory device through the use of data grouping and assignment of data validity status values to grouped data. For example, data is received and delineated into one or more data groups and a data validity status is associated with each data group. Data groups having a valid status are latched into one or more cache registers for storage in an array of memory cells wherein data groups comprising an invalid status are rejected by the one or more cache registers.

Abstract: A non-volatile memory device includes a block remapping system that offsets an input block address by the addresses of non-functional blocks to provide an output block address that is used to address the memory device. The system generates the output block addresses by, in effect, adding to the input block address the addresses of all non-functional blocks of memory that are between an initial address and the output block address. The system performs this function be comparing the input block address to the address of any defective block. If the address of the defective block is less than or equal to the input block address, the addresses of all defective blocks starting at the block address are added to the input block address. The system then iteratively performs this process using each output block address generated by the system in place of the input block address.

Abstract: The present description relates to non-volatile memory arrays and the operation thereof In at least one embodiment, the non-volatile memory array may include a plurality of memory modules coupled in a daisy chain with enable in/out signals, and a single chip enable signal coupled in parallel to each memory module. With such a configuration, all memory units within each of the memory modules of each memory array may be addressed with the single chip enable signal.

Abstract: Methods for sensing, memory devices, and memory systems are disclosed. In one such memory device, a local sense circuit provides sensing of an upper group of memory cells while a global sense circuit provides sensing of a lower group of memory cells. Data sensed by the local sense circuit is transferred to the global sense circuit over local data lines or a global transfer line that is multiplexed to the local data lines. An alternate embodiment uses the local sense circuit to sense both upper and lower groups of memory cells.

Abstract: A fast data access circuit that has both a standard clock mode and a fast data access mode. The mode is selectable through a mode/configuration register. A configuration word loaded into the register has bits to indicate the desired mode and the input clock frequency. In the fast data access mode, a clock delay circuit uses the clock frequency setting bits to select a delay to be added to the input clock. The higher the clock frequency, the less the added delay. The delayed clock generates FIFO control signals to control a data FIFO register. During the fast data access mode, the data is output from the data FIFO register at a faster rate than in the standard clock mode.
